+ Reworked the way DEVMODE structure is handled. As many winapi
interfacing methods, this is also a strange beast, it contains
some hidden information, so it must be created using some
winapi calls. I finally settled with these three functions
to handle DEVMODE structure from .prg level:
__WAPI_DEVMODE_NEW( <cPrinterName> ) => <pDEVMODE>
__WAPI_DEVMODE_SET( <pDEVMODE>, <hashToWriteFrom> )
__WAPI_DEVMODE_GET( <pDEVMODE>, <hashToReadInto> )
Then <pDEVMODE> can be passed to WAPI_CREATEDC() and WAPI_RESETDC().
Remember to recreate <pDEVMODE> after using __WAPI_DEVMODE_SET()
and before using __WAPI_DEVMODE_GET() to refresh the structure
content with actual device settings.
